Intercell AG (VSE, "ICLL") announced today that the safety analyses
for the pivotal Phase III safety trial of its investigational
Japanese Encephalitis vaccine are positive.

The pivotal Phase III safety trial was conducted at 39 study sites in
Austria, Germany, Romania, Israel, Australia, New Zealand and in the
US, and included 2,683 randomized subjects. The study was designed to
analyze the safety and tolerability of Intercell’s investigational
vaccine in a multicenter, multinational, double-blind,
placebo-controlled randomized study.

Major endpoints of this study were the frequency of adverse events in
both test groups, as well as local tolerability findings in both
groups. First analyses of this trial show that Intercell’s
investigational Japanese Encephalitis vaccine was systemically and
locally well tolerated. Overall, the local tolerability and general
safety profile of the Intercell JE vaccine appeared to be comparable
with placebo.

The Phase III clinical trial program consists of several additional
clinical trials including a pivotal immunogenicity trial, a single
shot trial, and a co-vaccination trial for travelers, which are all
expected to be completed by early 2007. To date, more than 4,800 of
the approximately 5,370 trial participants have been enrolled and
vaccinated in these clinical trials. The pivotal Phase III clinical
trial program is designed to meet regulatory requirements in the
United States, Europe and Australia. Assuming approval by the
regulatory authorities, the first market launch is anticipated for
2007. Preparations for the submission of a BLA (Biologics License
Application) to the FDA have commenced.

Full clinical results of the pivotal immunogenicity trial are planned
to be presented at the Annual Meeting of the American Society of
Tropical Medicine and Hygiene (ASTMH), November 12-16, Atlanta, and
full clinical results of the pivotal safety trial are planned to be
presented at the 10th Conference of the International Society of
Travel Medicine, May 20-24, 2007 in Vancouver, Canada.
